Best boost gauge for superchaged corvette free#
Kenne Bell standard kits are engineered to perform slip free with the belt and pulley supplied in the kit. The cure for this problem is to replace any leaking fittings or lines and correctly route vacuum/boost lines to their intended locations. If the bypass valve opens and closes with the corresponding boost and vacuum inputs from the hand held pump, then the problem is a leak or incorrect routing of the vacuum/boost lines as this test eliminated the valve itself as the source of the problem. WARNING: DO NOT operate the supercharger with the bypass valve closed all the time as this can lead to an non-repairable failure of the unit.Īny leaks in the supply line(s) or fittings that connect to the bypass valve can bleed off the air pressure and/or vacuum required to operate the valve properly.

The cure for this problem is to check for full travel (boost and vacuum) with the hand held pump and replace the bypass valve is its not operating properly. Most valves on Kenne Bell kits can be operated manually by moving the diaphragm arm up and down. Use the vacuum mode to check vacuum opening. Pressurize the line to the valve diaphragm to see if it closes completely. Check valve operation with a handheld vacuum/pressure pump (i.e. For example: An open bypass valve may register 1psi on a 6psi kit but 2psi on some 9-10psi kits. An open valve will bypass most but not all of the boost at WOT (wide open throttle). The bypass valve is “open” during vacuum and closes under boost. The cure for this problem is to re-route lines as per instructions. The boost gauge line must be connected to the discharge (boost) manifold fitting. The cure for this problem is to replace the pinched or severed line. Obviously a pinched or severed boost line will also not register boost accurately, or at all. The cure for this problem is to replace the defective lines and fittings.

The gauge is not reading leaks, but instead, only the nominal manifold vacuum of a big air pump. NOTE: Never assume an engine does not have a vacuum leak because the gauge reads “good”, “high”, or “plenty” of vacuum. Any leak will “bleed off” boost and give a lower, inaccurate reading. An accurate boost reading requires all the air to reach the gauge so you need to diagnose a problem with a vacuum/boost line leak first. The cure for this problem is to replace the gauge.Ĭheck ALL lines, fittings, and connectors that connect to the gauge, including line “T”s that are connected to the bypass valve, regulators, etc. We’ve seen boost gauges vary by as much as 2-3psi. The following list will help you to understand and analyze boost problems: Defective Gauges:įirst, compare your boost gauge with a gauge of known accuracy. Test and replace the gauge or repair the line or fitting leaks FIRST. That may tell us the supercharger kit is performing but the gauge is not.

Occasionally a customer will tell us “The car feels incredible, but the boost is low”. Instead, low boost is typically caused by non-stock cams, altered cam timing, headers, cat back exhaust, belt slippage, incorrect pulley size, inlet restrictions, kit modifications, increased engine displacement and/or efficiency, underdrive crank pulleys, defective gauges, leaky boost/vacuum links and fittings, weak tensioner, belt manufacturer (belts that stretch too much), etc. When a low boost condition exists we can almost always rule out the supercharger itself as the problem. They don’t vary so a “low” or “high” condition can never be attributed to the supercharger. Our superchargers are high precision air pumps that are incredibly consistent in performance.
